To all io/lont t may concern:

Be it known that l, ianvil) Bnoniia, a citi- Z-en et the United States. and a resident or" Los Angeles. in the county ot' Los Angeles and State ot California, have invented certain newand useiul Improvements in Hat Stretchers, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide means for stretching or varying the size othat trames; to obtain a uniform stretching pressure at a plurality ot points; to provide an apparatus as characterized, the sections ot which are guided in their action to obtain a more uniform pressure.

Drawings.

The present invention has for one of its principal objects to exert a stretching pressure simultaneously on ya number of points or portions of the hat shape or crown rather than as heretofore on two portions of the hat ban-d.

lVith this object in view, a number ot segments which when united form a mold having an outer shape substantially as shown in the drawings. Preferably the segments are shaped to provide a plurality of circumferential molds ot' different diameters such as are indicated by the designating numerals 11 and 12, the former indicating the more constracted section, and the latter numeral the more expanded section.

rllhe segments which form the mold are preferably made ot any suitable light weight metal. The segments have each7 end eX- tended tongues 13 which in service lit grooves 14 formed in each ot the adjacent segment-s. rllhe tongues 13 are disposed in staggered relation as best seen in Fig. 2 ot the drawings. The tongues thus torni interlocking or aligning members for maintaining the operating relation of the Various segments when the same are expanded.

A similar purpose is served by the top sector extensions 15 with -which each of the segments is provided. The sectors 15 are arranged in pairs, vone pair being assigned to each of the segments. Each pair is divided by the end-opening slot 16, opening'toward the center ot the mold. The slots 16 are furnished to receive the splines 17 with which a relatively stationary cover 18 is provided. g

The splines 17 as best seen in Fig. 2 of the drawings are extended radially from the center hub 19 with which the cover 18V is provided. The purpose of the hub 19 is to receive an inner cover 20, which as seen best in Fig. 3,01 the drawings completely covers the sectors 15 and the splines 17. Thel cov-er 2O is secured to the hub 19 by tastening members 21 such as screws shown in the drawings.

The hub 19 forms a bearing for a pivot member 22. The pivot member 22 as shown best in Fig. 4 ot the drawings has preferably a screw, the threaded end of which engages the end of the feed screw 23. The screw A2,5 is centrally located in the stretcher and has a winged head 24 which enables the operator to manipulate the screw readily. The threads of thescrew 23 engage the threads in the blocks 25 and 26 through which vis impartedto the segments of the stretcher, the expansive and contractive movement of said segments.

As best seen in Figure 3 otl the drawings, the block 26 has bracket extensions 27 disposed in parallel relation. The bracket eX- tensions 27 are elongated and are provided each with a pintle shaft 28, each ot which serves as a pivot for the spring of the links 29.

The opposite end of each of the links 29 is pivotally mounted on a pin 30 in brackets 31 in the side of the segments. Each segment it will be understood has brackets 31 and links 29. It will be noticed that the walls of the brackets 27 being disposed in parallel relation they operate on the links 29 as guides to hold the same in working position.

In operation the winged head 24 1s lirst turned to contract the segments so that they enter the inside ot the hat crown freely. It the hat crown lits the upper or smaller section, this only is placed within the crown. lt on the other hand it lits the lower sect-ion, the stretcher is inserted within the crown until the said lower section aligns with the sweat band of the hat. The stretcher being placed, in this manner; the operator manipulates the scr w so that the blocks and 26 are caused to travel lengthwise ot the said screw and toward the open end of the stretcher. The said blocks moving in the manner mentioned approach the outer end ot' the screw becoming interposed between the brackets 3l to which they respectively belong, with the result that the said brackets and parts associated therewith are movedA outward from the center of the stretcher.

As is seen best in Fig. e ot the drawings, the links 29 are held in parallel relation, the blocks 25 being moved by the same screw 23 at the same rate. The parallel relation ot the said links is at all times maintained.

ln the movement ot the lseg/ments ot' which the stretcher is composed; it will be observed, they are guided by the splines 1T which are connected to the cover 18. The cover 2O prevents the screw 23 liiting the segments of which the stretcher is formed by holding the sectors l5 in position and in guided relation to the splines 17.

l. A hat stretcher comprising a plurality ot' form segments corresponding substantiallyY to the shape ot' a hat for personal wear; a plurality ot covers disposed in spaced relation; engaging portions of said segments for controlling the movement thereof to and from the center ot the stretcher; a screw member; and a plurality of links pivotally connected to said segments and operatively connected with said screw whereby the inner ends oi' said links are caused to travel in parallel relation to the axis ot' said screw.

2. A hat stretcher comprising a plurality of form segments shaped in correspondence with the interior of a. hat of personal wear; a plurality ot covers held in permanent spaced relation for engaging said segments to permit the same being mov-ed to and from the center or" said stretcher; a feed screw pivotally connected with said covers; a plurality of travelling nuts mounted on said screw; and a plurality ot' links pivotally connected each to one ot said segments and to one oit' said nuts.

3. A hat stretcher comprisimg` a plurality ot' torni segments shaped in correspondence with the interior ot' a hat of personal wear; a` plurality ot covers held 'in permanent spaced relation tor engaging said segments to permit the same being moved to and from the centenot said stretcher; a feed screw pivotally connected with said covers; a plurality ot travelling nuts mounted on said screw; oppositely disposed pairs of parallel spaced arms on each of said nuts and a plurality ot links pivotally connected each to one ot' said segments and between a pair of said arms and movable therebetween to prevent rotation ot said nuts.

A hat stretcher comprising a plurality ot i'ormed segments7 a top cover plate, a hub centrally disposed on said plate, a bottoni plate attached to said hub and disposed throughout its major portion in parallel spaced relation to said top plate, sectors toi-med on said segments and slidable between said plates, a feed screw pivotally connected to one ot' said `cover plates; a plurality ot traveling nuts disposed on said feed screw and link connect-ion between said nuts and segments tor moving said segments ou rotation ot said screw.
